copy 3 Chelidon erythrogaster. Lake Umbagog, Maine. Nesting under the roof of a piazza. 1897. Mr Chandler showed me a Barn Swallow sitting on a nest June 13. placed under the roof of the piazza nearly over the front steps and within two or three yards of the front door of the house. The nest- which rests on a square timber about 8 ft. above the floor- was occupied two years ago by a Robin which reared a brood in it. Last year it was unoccupied. No one knows just when or by what bird it was built originally but it looks most like a Robin's nest and it has certainly been in its present position for three or four years. Of course the Swallows have added a feather lining. C. tells me that the two Swallows take turns at incubating and change places every 15 or 20 minutes (I saw this for myself two days later). They pay no attention to the people walking or sitting beneath them and yesterday one of the young men, standing nearly under the nest, fired upwards of fifty shots from a rifle without disturbing the sitting bird. 38
